Substation · Renewable
The Enterprise Substation was designed and constructed to connect a 34.5kV Collector System from the SunEdison owned 80MW Enterprise Solar Project in Iron County, Utah, and provides a path to market for the new solar project. As part of an Engineer-Procure-Construct (EPC) team, M&S Engineering design personnel provided all engineering design associated with the new substation.
The project consisted of an open air substation with (2) 138/34.5kV, 89 MVA, power transformers. Both transformers are equipped with 138kV load tap changers. One of the power transformers is setup as a spare and is located at the Enterprise substation for long term storage on site within the substation fence. There is also (1) 138kV SF6 breaker, (2) 34.5kV vacuum feeder breakers, (1) 34.5kV capacitor bank vacuum breaker, (2) 34.5kV 4850KVAR capacitor banks with integrated circuit switchers, protective relay devices, and other apparatuses as required by the interconnecting agreement. M&S Engineering provided detailed design for all civil, structural, electrical, foundations, and system protection coordination review with relay settings.
Power flow, short circuit analysis, protection coordination, arc-flash, harmonic analysis and other complex studies, such as transient overvoltage (TOV), capacitor switching, and Ferro-resonance studies were performed by Electric Power Engineers via subcontract. SCADA design, integration and commissioning was performed via subcontract by Sebesta, Inc.
This is the start of a Successful Relationship
Highest Level of Professional Engineering
M&S has been Southstar’s Civil Engineer for over 7 years and our success is a direct result of their stellar work. From their leadership down to the company’s focus and ideals M&S represents the highest level of professional engineering. They are focused on their client and understand our goals and challenges. Southstar would not be the company nor our projects be the success they are unless we had M&S by our side.
Focused on Developing Relationships
This partnership we have forged will launch our District well into the future. With a supportive Board we have focused on developing relationships that bond us with our consultants as partners rather than tools that we use. We feel that we have a very symbiotic relationship with our team at M&S.

Project Coordination Heroes
M&S is one of the most responsive firms that I have worked with, which improves our project coordination process.
Tim S. Gescheidle,
The staff at M&S has been fundamental in building the CIP for Crystal Clear SUD and in guiding the board of directors in all aspects of the overall concepts utilized. They have been able to explain things in manageable segments that have assured understanding at all director experience levels. We greatly appreciate their professionalism and true partnership with the Crystal Clear organization.
